This is the most fun I've had all week. Thanks for starting it, Rachylou, and thanks everyone for sharing! (I've been envisioning plants draped in jewellery...inspiration for my annual pin-the-bright-mini-lights-on-the elephant ears holiday decor...)
Like Laura, I'm understudying Team Spotless Whites in Any Situation, but I'm also noted for my unerring ability to Hone in on the Most Expensive Item in any bricks-and-mortar store.
Still, I think my strongest Superpower is Online Ordering. I can almost always pick the right item and size based on reviews -- I am even brave enough to order bras and shoes! As Celia said of her own Superpower, mine is not innate but I have carefully cultivated it ever since I joined YLF.
